The invention discloses a method of replacing a conveying belt of a ship self-unloading system with a new one. The method includes the steps of preparing tools, installing the tools and replacing theold belt with a new one. In the step of preparing the tools, four hoist cranes, a pair of U-bar clamping plates, a new belt put-down device, an old belt take-up device, a chain block, a winch and a belt pulling tool are prepared in advance. The step of installing the tools includes the substeps of firstly, pulling an inner side belt tensioning wheel on an inner side belt tensioning wheel support of the ship self-unloading system by two hoist cranes instead of original inner side belt tensioning oil cylinders, and pulling an outer side belt tensioning wheel on an outer side belt tensioning wheel support of the ship self-unloading system by another two hoist cranes instead of original outer side belt tensioning oil cylinders; and secondly, installing the pair of U-bar clamping plates below an inner side belt discharge port, wherein the pair of U-bar clamping plates elastically clamp the old belt as an inner side belt. By means of the method, the cabin conveying belt of the ship self-unloading system is rapidly replaced with a new one.
